Re: Generic views and url issues

Hi Amy,

I'd suggest you check the following...

* Your ROOT_URLCONF setting is correct.
* If the `urls.py` module you're referring to here is a project URL conf and not the root URL conf, make sure that it is being included by the root URL conf.  (This seems like the most likely cause)

* If it is being included by the root URL conf, check if it's being included with a `namespace` argument, and if so make sure to prefix the reverse with the appropiate namespace, eg if it's namespaced as 'myapp', then use 'myapp:addcalls'.

You've already made things really simple, the URL conf as you've declared it looks correct, so this...

   Reverse for 'adcalls' with arguments '()' and keyword arguments '{}' not found.

Suggests that 'adcalls' simply isn't included part of the URL conf of the application.

Cheers,

  Tom

Thanks for your response!

Unfortunately, your suggestion did not eliminate the NoReverseMatch error.

NoReverseMatch at /testadcall/

Reverse for 'detail' with arguments '()' and keyword arguments '{'object_id': 1}' not found.

I have another example where I request the list view, which does not expect arguments, to keep it even simpler.

urls.py

queryset = {'queryset': Adcall.objects.order_by('name')}

urlpatterns = patterns('django.views.generic.list_detail',

    url(r'^$','object_list', queryset, name="adcalls"),

    url(r'^(?P<object_id>\d+)/detail/$', 'object_detail', queryset, name="detail"),

)

template:

EDIT TEMPLATE

{% load url from future %}

<form action="" method="post">{% csrf_token %}

{{ form.as_p }}

<input type="submit" value="Submit" />

</form>

<a href="{% url 'adcalls' %}">Back to adcall list</a>

Error:

NoReverseMatch at /testadcall/1/detail/

Reverse for 'adcalls' with arguments '()' and keyword arguments '{}' not found.

I've been trying to understand how to use generic views.  I've followed some tutorials, and read through Django docs, but I can't get the url function to work in my templates.

I get the error
NoReverseMatch at /testadcall/
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}' not found.

in my urls.py

queryset = {'queryset': Adcall.objects.order_by('name')}

urlpatterns = patterns('django.views.generic.list_detail',
    url(r'^$','object_list', queryset, name="adcalls"),
    url(r'(?P<object_id>\d+)/detail/$', 'object_detail', queryset, name="detail"),
)

in my template for the list view:

{% load url from future %}
{% if object_list %}
    <ul>
    {% for adcall in object_list %}
        <li><a href="{% url 'detail' adcall.id %}/">{{ adcall.name }}</a></li>
    {% endfor %}
    </ul>
{% endif %}

I've tried no quotes, single quotes, and double quotes around the url name "detail", with no apparent effect.

Am I wrong in thinking that this should work?

The problem is a mismatch between your urls.py pattern and the parameters you give to the url templatetag - note in the error message that it mentions both arguments and keyword arguments (with your example having a single non-keyword argument). However, in your url pattern for the "detail" url, you use a named capture (object_id). In this case, you must use a keyword argument to match:

{% url 'detail' object_id=adcall.id %}

Regards,
Michael.
